fs and path modules example

Read the current directory, determine object is file or not, extract files extension and basename, print them out.

'use strict';

var fs = require('fs');
var path = require('path');

fs.readdir('./', (err, files) => {
    if (err) {
        console.error(err);
    }

    for (let file of files) {
        fs.stat(file, (err, stats) => {
            if (stats.isFile()) {
                let ext = path.extname(file);
                let basename = path.basename(file, ext);

                console.log(`File ${basename} with extension ${ext}`);
            } else {
                console.log(`Object ${file} is not a file.`);
            }
        });
    }
});
